Django 服务器上的迁移问题

我已将django项目部署到digital ocean服务器，并成功安装了所有需求。但是，当我在makemigrations之后运行migrate时，会出现以下异常：

django.db.utils.ProgrammingError: relation "auth_permission" already exists

Operations to perform:
  Synchronize unmigrated apps: formtools, django_filters, djcelery, storages

我怎样才能解决这个问题-请帮忙

似乎您的迁移和数据库已取消同步

尝试重新创建数据库，然后运行./manage.py migrate

---

另外，您不应该在服务器上运行./manage.py makemigrations。看一看。

您不应该在服务器上运行makemigrations。您可以在本地、在开发机器上这样做，并将它们提交给源代码管理。然后在部署时运行实际的migrate命令

---

目前，您可能需要在服务器上删除并重新创建数据库，然后重新运行迁移。

目前，您可能需要在服务器上删除并重新创建数据库，然后重新运行“迁移”。

您不需要手动升级Django-当您使用更新tendenci时，Django将与其他依赖项一起自动升级

pip install -r requirements/tendenci.txt --upgrade

或者只是

pip install -r requirements.txt --upgrade

请卸载Django和DjCellery，然后运行上述命令。你可能需要假芹菜0001

python manage.py migrate djcelery 0001 --fake

---

请注意，tendenci当前与Django 1.8.x兼容。

最后，我不得不删除我的数据库，并按照前面回答中的建议重新创建

根据我的经验，尽管早晚将迁移文件推送到服务器是不可取的，但最终会导致灾难。在您的服务器上运行makemigrations—这将确保数据库的完整性。

这是您第一次应用迁移吗？是的，目前还没有迁移文件。这是新安装的。这是您第一次应用迁移吗？是的，目前还没有迁移文件。这是新安装的
